IMPROVEMENT IN WATER-GAUGES FOR STEAM-GENERATORS.

TO ALL WHOM IT MAY CONCERN:

Beit known that I, EMMETT QUINN, of Washington, District of Columbia,have invented a new and improved Water-Gauge; and Ido hereby declarethat the following is a full and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon.

Thewnature of my invention consists in the construction of the gauge,whereby I am enabled to avoid the use of the glass tube ordinarily usedfor such purpose, and substitute one composed of iron, or other suitablematerial, and plate-glass, and which is capable of being repaired at anytime without being detached from the boiler. This gauge is also providedwith facilities for cleaning or washing out the tube when soiled or dimfrom use.

To enable others skilled in the art to construct my invention, thefollowing description is sufficient.

Figure 1 is a face view.

Figure 2, a. View of section on line a: 11:.

Figure 3, a view on line y Figure 4, a side View of a verticalsection ofthe top on line z z, fig. If and Figure 5, same view of the bot-tom parton line 2 2, showing the manner of admitting waterfrom the boiler to andshutting it oh from the gauge.

The main body A A, forming the sides and ends of the tubes, is one pieceof cast iron, surrounded at top and bottom by wrought-iron rings orhands a a. To each end of the piece A'A is secured, by means of screwscc, the pieces containing the sockets ,intowhich the pipes connectingthe gauge with the boiler are inserted. That at top, shown in fig. 4,for the admission of steam; the one at bottom, fig. 5, for water, andthis piece also contains a three-way cock, F, for shutting oh the waterfrom the boiler and permitting afree passage for the steam outward orthe introduction of a wiper into the tube when it becomes soiled andneeds cleaning. The front and rear sides of the tube are of plate-glass,B B, between which and the piece A A are packing pieces '66, the wholesecured firmly together by screw passing through the four wrought-ironclamps G C C O, as shown in fig. 2. The scale or index-plates are ofwhite metal, and .can be marked, as shown in fig.- 1, to denote theposition of the water in the boiler when at above or below the properlevel. A modification of this construction is shown in fig. 6, in whichthe cast-irou portion forms all parts of the gauge but the front plateof glass and clamps therefor,'but as the-water would show tooindistinctly in such a gauge it is not considered the best, but may withsome improvements be made the subject of a subsequent application.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

As a new article of manufacture, awatcr-gauge, consisting of the metalframe with the glass platesB secured thereto on opposite sides, asherein'shown and described.
